Woomeri drew CASA's attention to the PPRuNe threads. I would not suggest CASA religiously "monitor" these pages, however it's a fair bet far more people read these pages than care to admit - after all, PPRuNe gets over a million page hits per day. And if a regulator wants to stay in touch with industry thinking, PPRuNe is one measure available.
After all, this is a public forum with both significant aviation industry user contribution and significant readership.
